Description:
Method for controlling an elevator
The invention relates to a method for controlling an elevator, wherein a user of the elevator communicates a travel request by means of a man/machine interface to the elevator which executes the desired journey.
There has become known from the patent specification US 5 832 363 a communication system for transport equipment with elevators. A management plane superordinate to the transport equipment manages the transport equipment on the basis of specific operational data. If a potential user carries a radio telephone, his or her position is continuously ascertained. If the user moves to an elevator entry, an elevator car is ordered to the desired stopping point by the management plane.
A disadvantage of the known equipment resides in the fact that the user has to input his or her travel destination at the storey or in the elevator car. In the case of crowding at the storey or in the elevator car the user is stressed and loses time for the command input, whereby false inputs can also arise.
Here the invention will create a remedy. The invention, as characterised in claim 1, fulfills the object of avoiding the disadvantages of the known equipment and of creating a method by which the control of an elevator installation is made more user-friendly.
The advantages achieved by the invention are substantially to be seen in the fact that the user can use an individual control unit which is trusted by the user and which makes possible a locally fixed control by the user of the elevator installation. Moreover, there can be made available to the user, on the individual control unit, information about the elevator installation, the building and the use of the building. It is further of advantage that the user during the control and utilisation of the elevator installation is reachable at any time. The user can thus be assisted during the control and/or on his or her way with further information, such as, for example, details about transfer storeys and changes in the car allocation, or with details and instructions relating to a fire situation. It is further advantageous that no or only a few locally fixed control units are necessary, because each

user carries his or her own control unit therewith, which is also usable for other communications services.
The control unit is temporarily used for control of the elevator, wherein the control unit is provided for a specific time with functions which enable elevator control. For that purpose the necessary program and data are communicated to the control unit, are executed and evaluated therein and subsequently obliterated. By virtue of an identification of the control unit, this can be addressed by the elevator installation and information can be communicated thereto.
The present invention is explained in more detail on the basis of the accompanying figures, in which:
Fig. 1 shows computer equipment connected with an elevator installation and with
a mobile radio network,
Fig. 2 shows a local mobile radio network connected with the computer equipment
and
Figs. 3 to 10 show a menu for control of the elevator installation and for informing the user.
Fig. 1 shows the necessary hardware equipment for control of an elevator installation, which is denoted by 1 and 2, or of an elevator by means of a usual commercial radio telephone 3 as control unit for the elevator. The radio telephone 3, which is also termed mobile telephone, comprises a keyboard 4 provided as a data input unit and a display element 5, also called display, provided as a data output unit. The mobile 3 telephone can communicate in wire-free manner with a mobile radio network 6, wherein speech and/or data are transmissible. For the transmission of speech and/or data the mobile radio network can be placed in connection with further mobiles telephones or with computer equipment denoted as terminal 7. The terminal 7 consists of a computer system denoted as server 8, which has access to a memory 9 with elevator-specific and/or general information. The server 8 is also connected with the elevator installation 1, 2 by means of an interface 10. Mobile telephone 3, mobile radio network 6 and terminal 7 form a man/machine interface between the user and the elevator installation 1, 2.

static information for elevator control, for example in the form of defined WML (Wireless Markup Language) pages and scripts is stored in the memory 9 and can be accessed by the server 8, Programs which can produce situation-induced information can also be filed in the memory 9. The server 8 can, in addition, make dynamic information and elevator functions available via interface 10. If the mobile telephone 3 is capable of interpreting information based on the WAP standard (Wireless Application Protocol), the informatioii can be loaded at the mobile telephone 3 and made available at the mobile telephone 3. With the WAP standard the information is prepared for the mobile telephone in that graphical ballast is reduced and the information is optimised for small screens. The mobile telephone 3 must have available an interpreter denoted as browser, by means of which the information can be loaded and the offered elevator capabilities utilised and the information represented.
For control of the elevator installation, the terminal 7 as setting representative of the elevator installation 1, 2 is called up by the mobile telephone 3 according to address. Thereupon the information (WML page) associated with the address is transmitted to the mobile telephone 3 and represented on the display 5 by means of the browser of the mobile telephone. If an elevator journey is desired, then the mobile 3 telephone demands corresponding WML pages from the server 8 and, if needed, supplementary WML scripts according to the WML page active in the mobile telephone 3. For preparation of this information the server 8 of the memory 9, which as explained further above contains the WML information and/or program for producing the WML information, serves itself. In addition, supplementary, elevator-specific information accessible by means of the interface 10 can be incorporated. The control of the elevator installation 1. 2 then takes place through selection on the WML page by means of the keyboard 4. As response to the selection the elevator installation 1, 2 makes available to the user further information, for example the elevator allocation in the case of an elevator group, the travel time, etc., via the WML page on the display 5.
The communication between mobile telephone 3 and server 8 is usually carried out in the manner that the information has to be expressly requested at the server 8 by the user by means of the mobile telephone browser. In the case of the WAP standard there is the new addition that the server 8 transmits data to the browser without this making an express wish. The browser desires at the server 8 a WML initial page which usually enables all

inputs necessary for an elevator journey, such as, for example, boarding storey and destination storey. After the data input a demand with the data goes to the server 8, which books the desired journey at the elevator control 2 and which obtains from the elevator control 2 the allocation of the elevator car. The server 8 combines this information with possible further information as WML content and transmits this to the mobile telephone browser.
The mobile telephone 3 can, as shown in Fig. 1, communicate with a mobile radio network 6. The mobile radio network 6 can be a global or a publicly accessible mobile radio network 6 or, as illustrated in Fig. 2, a local mobile radio network 6. Global and local mobile radio networks 6 can also be operated in parallel. Fig. 2 shows a local mobile radio network 6 referred to a building MAN. The three storeys E1, E2, E3 of the building MAN are connected with an elevator shaft 1.1, in which an elevator car 1.2 is movable. In the simplest case, the terminal 7 has available a local network 6 with a cell ZE in the entry region of the building MAN, with a respective cell Z1, Z2, Z3 in the lobby region of the elevator entrances and a cell ZA in the elevator car 1.2. Each cell ZE, Z1, Z2, Z3, ZA is produced by a nodal point KE, K1, K2, K3, KA based on, for example, Bluetooth technology. A nodal point KE, K1, K2, K3, KA produces a cell and is connected with the terminal 7. For production and reception of an electromagnetic field the nodal point comprises a transmitter/receiver unit with an antenna unit and a converter. The operative range of the nodal point corresponds with the cell. Bluetooth technology comprises a method for wireless communication by means of radio connection in the GHz region. In that case the transmission of data and speech is assisted and methods for formation of networks in the form of cells and cell compounds are provided. Through limitation of the transmission power, direct point-to-point connections are possible only at close range. A mobile telephone with a Bluetooth module can communicate with the local mobile radio network 6 of Fig. 2 on the WAP standard.
If a user is detected within a locally distinct cell ZE, Z1, Z2, Z3, ZA, then the communication content between the control unit 3 and the terminal 7 is supplemented by the local information of the corresponding cell. The terminal 7 can then associate each user request with a specific local region.
Local information can also be obtained by a system for positional determination of the i user, for example by GPS (Global Positioning System). The ascertained local information

is transmitted to the server and used for construction and checking of the course of the controlling. With the local information, for example, the boarding storey can be ascertained and/or guidance of the user within the building MAN, warning of the user in the case of going wrong, etc., can be managed.
Connections from the control unit 3 to building services external to the elevator are also possible if interfaces to the corresponding building services are present in the terminal 7 and the relevant WML contents are filed in the memory 9. Building services of domestic technology, such as, for example, control and checking of heating installations, lighting installations, doors, equipment for identification of users and access to the building, monitoring installations, internal building telephone networks, building information equipment, etc., are reachable from the control unit 3.
Communication between the control unit 3 and the terminal 7 can also comprise user-specific information, for example identification data of the user or data for release of special functions or user data which, for example, enables association of the costs for the elevator utilisation.
Figures 3 to 10 show a menu-guided communication of the user with the terminal 7. On entering the building MAN, the user calls up the corresponding address of the elevator installation or building, whereupon the terminal 7 prepares the corresponding building information and delivers it to the mobile telephone 3. The information is made available to the user on the display 5 of the mobile telephone 3 in menu form. As shown in Fig. 3, the user knows which department he wants to visit. He selects the menu point 'Departments'. In Fig. 4 the interrogation is refined. The user wants to visit the personnel department and selects the corresponding department 'CHR' As shown in Fig. 5, the terminal 7 recognises the storey of the personnel department and the contact person. The visitor wants to personally meet the contact person and consequently selects the second menu point of Fig. 5. The necessary parameters for the elevator journey are thus known. Fig. 6 shows the allocation of the elevator car. The user boards the elevator car A and travels to the storey 6. As shown in Fig. 7, the user is informed in which office the contact person of the personnel department is to be met. With the menu according to Fig. 8 the user can seek other localities or leave the building. If the visitor wants to leave the building, an elevator car is assigned to him or her. Until departure from the building, the user is reachable by way of his or her address. In the case of need, further information can be

made available to the user as shown in Figs. 9 and 10. On leaving the building, the information made available in the mobile telephone 3 by the terminal 7 is erased. The mobile telephone 3 then again serves as an individual communication means of the user for speech and/or data.
